Your pets deserve gifts, too. Fill your cat, dog or ferret's stocking with treats, toys and other goodies that you bought at a heavy discount on Black Friday. And be strategic by stocking up on dog food for the year.

Best retailers for Black Friday pet supply discounts

Petco holds a Black Friday sale every year. In the past, highlights have included buy-one-get-one-50% off food from select brands, BOGO specials on chews, 50% off treats and 25% off toys.

Petsmart: Petsmart also holds a strong Black Friday sale, which has included such deals as dog beds under $20, 50% off pet clothing and up to 50% off crates.

The best part is that, at these stores, your pet can wait in line and shop with you.

Wherever you shop for your pet on Black Friday, in addition to getting your pet a Christmas costume and plenty of holiday treats, use the discounts to get some bigger-ticket items, such as pet beds, cat trees, automatic feeders and pet cams (such as the Petcube). Black Friday deals on these items will turn them from pricey luxuries to things that might be in your budget.
